```zig
pub fn buildSheet(scope: *ui.Scope, cx: *ui.Cx) anyerror!*ui.Node {
    const a = cx.allocator;
    const c = try col(cx, 12);
    const vis = try scope.createSignal(bool, false);
    const st = try cx.bindState(SheetStory, .{ .visible = vis });
    const sbtn = try W.Button(.{ .label = "Open Sheet", .on_click = cx.on(SheetStory, st, SheetStory.open) }).mount(scope, cx);
    sbtn.meta.ownership.meta.test_id = "story.sheet.open";
    try c.appendChild(a, sbtn);

    const sh = try W.Sheet(.{ .side = .right, .width = 320 }).visible(vis).mount(scope, cx);
    sh.panel.meta.ownership.meta.test_id = "story.sheet.panel";
    try sh.content.appendChild(a, try ui.text(cx, "Sheet panel content.", .{ .font_size = 14, .color = light.color.fg_primary }));
    if (!sh.portaled) try c.appendChild(a, sh.overlay);
    return c;
}
